MACHINE FOR DYEIN G YARN ON THE SKElN.

SPECIFICATION forming part of Letters Patent No. 402,648, dated May 7, 1889.

Application filed October 20, 1888.

To all whom it may concern.-

tion.

Our improvements relate to machines of this class by means of which the work can be more expeditiously done at a great saving of time and labor, and in which a more thorough saturation of the yarn is secured, and these objects we accomplish by the mechanism illustrated in the accompanying drawings, in

which Figure 1 is a side elevation of the machine, the broken part exhibiting a perspective viewof theinterior; Fig. 2,a front elevation of two reel-frames, in perspective, on the shaft; Fig. 3, a side elevation of keir and brake; Fig. 4, the perforated reelstick; Fig. 5, a cross-section of reel-stick and disk; Fig. 6, a cross-section of side arm of reel-frame and screw; Fig. 7, a View of reel-frame in detail; Fig. 8, a detail View of one-half of reel-frame for the side arm with the cap open; Fig. 9, a

refer to similar parts say, of five feet, with an interior dimension for any required quantity of dyeing or coloring matter.

B designates a solid substantial frame hav ing the supportingdegs b b and a solid crosspiece, b

0 designates a journal-box firmly, secured to the frame-work and bearing the shaftD of the wheel. This shaft maybe connected with any proper system of gearing which will im-' part a rotary motion to the shaft for a certain number of revolutions in one direction and Serial. No. 288,717. (No model.)

then a reverse rotary motion in the opposite direction. A similar journal box and bearing is provided for the opposite end of the shaft D on the opposite vertical post of the frame. Upon either end of the shaft and within the side walls of the heir are secured the flanged hubs E, revolving with the shaft.

The hubs are constructed of metal, (see Figs. 11 and 12,) with a broad fiange. e,e,

and e are ridges upon the inner surface ofthis flange, extending from the periphery to the axis of the hub, these ridges making a groove, into which the shoulder of the spoke fits. Forty of these ridges, forming twenty such grooves, we would prefer to construct.

F (see Fig. 11) designates one of a series of twenty spokes, preferably, for each hub, constructed of metal, with the longitudinal slot f extending from the end to the shoulder. The end of this spoke is hollowed out to form a bearing for the shaft of the reel-stick. Upon this spoke is constructed (see Fig. 11) a lock to holdvthe upper reel-stick in the bearing of the spoke. A

g designates the pin g securing the same to the spoke and bent to cover over the hollow made in the end of the spoke to form a bearing, as described.

' 'i represents a pin mounted vertically in a recess of the head upon a spiral spring. a" designates a shaft secured to this pin and extending from the recess through a slot to the outside of the head. This pin fits into a hole in the. bent end of the swinging arm and holds the same securely over the hollow bearing. To unlock this arm, it is merely necessary to press down the pin by means of the shaft z".

The shoulder j of ihe spoke fits into the an arm swinging loosely upon ICO and the main part of the stick. Through the shaft of the stick are drilled the longitudinal perforations a a, &c., extending entirely throughthe metal and forming in the interior of each stick two hollows. This construction is followed in each of the reel-sticks, and allows the unrestricted percolation of the dyeing-liquor through that portion of the skein resting upon the sticks.

N designates a friction-disk, mounted on the end of the shaft J of the upper reel-stick. (See Fig. 1.) This disk is mounted on the extreme end of the shaft, which is extended beyond the stick for this purpose.

y designates a rubber bunter secured to the under side of the cross-beam of the frame in such a position as to collide with the disk when the revolution of the shaftbrin gs the reelstick beneath the said cross-beam. e prefer this form of mechanism for imparting part of a revolution to the upper reel-stick, since the distance through which the yarn is to be moved is of necessity very slight, and this form of mechanism imparts a very gentle motion and occasions no displacement of the skeins.

The side arms of the reel-frame are constructed as follows, (see Figs. 7, 8, and 9:) Each side arm consists of two adjustable parts.

In Fig. 8 s designates a longitudinal slotted aperture.

1" and 1' designate slotted grooves, the groove 2" of the cap closing over the groove 1? when the cap is looked, as hereinafter described.

e and c are apertures having a corresponding thread, through which a screw passes to hold the cap securely looked upon the arm.

h designates a hinge for the cap.

In Fig. 10 11 and t are corresponding slotted grooves, c and a corresponding threaded apertures, and d a threaded aperture in the arm. In Fig. 9 these two sections appear in position with the caps locked and the arms secured for any desired length of reel by means of the thumb-screw 70, which looks the longitudinally-slotted arm by means of the threaded aperture (1 in the corresponding section. A like description applies to each one of the arms of the several reels. lVhen the length of these arms is properly adjusted, the shafts of the upper and lower reel-sticks are locked by means of the caps into the bearings formed by the slotted grooves 2 2' i i and the entire reel, Fig. 7, slides into the slot f of the spoke F, (see Fig. 11,) which is firmly secured to the hub E, as described.

The skeins of yarn to be dyed are set upon the reel-sticks, the distance between which is adjusted to allow the yarn to hang somewhat loosely, and the reel-frame then introduced into the slotted spoke F. The arm g is then looked, as described, and the reel-frame is then held firmly in position 011 the slotted spoke.

When the machine has been loaded to the desired capacity, motion is imparted to the main shaft and the reel-frames containing the yarn are plunged into the dyeing or coloring matter contained in the vat or keir and emerge on the other side. As the upper reel-stick, which, as described, is provided with a friction-disk, reaches a position under the crossbar of the supporting-frame, the disk comes in contact with a rubber bunter secured to said cross-bar and extending downward far enough to engage with the surface of the disk, and causes the reel-stick to make part of a revolution,and brings anew part of the skein in contact with the edges of the stick. When the yarn on the reel-frame has been plunged into the liquor any required number of times,

' the motion of the shaft is reversed and the opposite side of the skein plunged first into the bath, thus distributing the coloring-matter more evenly. \Ve desire to call attention to our method of introducing liquor into the tank while the shaft is in motion.

One end of the tank or keir (see Fig. l) is constructed with double walls and an airspace between the outer and inner wall extending to the bottom of the keir. Between the bottom of the keir and the lower edge of the inner wall a space is left extending the width of the keir, thus forming an unobstructed channel communicating with the outside. If, in the process of dyeing, it becomes necessary to change the shade of the coloring-matter already in the keir, additional liquor may be poured into this channel, and when the shaft revolves in the direction indicated by the arrow-head it will readily be seen that a current will be formed which will draw in the additional coloring-matter and thoroughly mix the same with that in the keir. This construction obviates the necessity of injecting .the additional liquor by force.

In Fig. 3 is shown our contrivance for holding the wheel locked while loading the reels upon the spokes.

In the drawings, P designates a cog-wheel mounted upon the shaft D.

R designates a lever swinging loosely upon the pin 1'; Q, a straight arm secured to the lever, moving forward and back by means of the guiding-slot w and two pins, w and w This lever engages with the gear P by the point q, and holds the shaft firmly locked.

S designates a spiral spring, and t a loose arm swinging upon a pin. WVhen the lever is pulled back, this pin drops over the pro jecting lip v of the arm Q: and holds the point of the arm away from the gear, allowing the shaft to revolve. By lifting up this loose arm the spiral spring will cause the arm Q again to engage with the gear.

\Ve are aware that previous to this application machines for dyeing yarn on the skein have been employed,-as by Letters Patent issued to Charles L. Klauder, dated February 7, 1888, No. 377,393, for a dyeing and scouring machine; but the advantages in our machine as constructed and described are, that by employing a reel-frame separate and distinct from the supporting arms or.

spokes, adjustable to any length of skein and contrived to slide into a groove of said spokes, the yarn can be loaded and unloaded away from the machine, and thus more expeditiously and securely handled that the capacity of our machine, using a comparatively equal size of keir and shaft, will be much greater for holding yarn, since as the loading and unloading are done off the machine the supporting arms or spokes can be placed more closely together on the shaft, thus allowing the use of a much larger number of reels; that a more perfect adjustment is secured by our machine in the construction as employed; that by the use of a perforated hollow reel-stick a more complete saturation of that part of the skein resting upon the stick by the liquor is secured, which would do away with any absolute necessity of employing mechanismfor changing the position of the skein on said sticks when,

in the process of dyeing, although in our machine we have described such means; that, owing to the reverse motionapplied to our shaft, both sides of the skein can be alternately plunged into the coloring-bath, and thus a more perfect saturation secured in a shorter space .of time and, again, additional liquor can at any time be added tothat in the vat Without any means for injecting the same.

We claim that in machines as at present constructed it is necessary, in the process of loading and unloading, to employ at least two men, or a man and a boy; but in our construction one man or one boy can easily load or unload the machine and attend to the same during the entire process of dyeing. .In dyeing yarn without a machine the services of two men are always required.

What we claim as new, and desire to secure by Letters Patent, is-

1. In a machine for dyeing yarn on the skein, the combination, substantially as hereinbefore described, of a tank containing dye or liquor, a frame secured thereto supporting a journalbox, a rotary central shaft alternately rotating in either direction, flanged hubs mounted upon the said shaft, longitudinally-slotted spokes secured to said hubs, a frame for holding the skeins of yarn fitting into the slotted groove of said spokes, and means for locking said frame into said spokes.

A 2. In a machine for dyeing yarn on the skein, the combination, substantially as hereinbefore described, of a tank, a frame secured thereto, a. rotary shaft, flanged hubs, longi- =tudinally-slotted spokes, means for holding vsaid shaft and spokes while in the process of loading and unloading, a frame for holding the skeins, adjustable for any length of skein, fitting into the slotted groove of the spokes, means for locking said frame into said spokes,

and a friction-disk, N, mounted upon the extended shaftJ of the upper reel-stick of the frame colliding with a bunt-er extending downward from the cross-bar of the supporting-frame.

3. The combination, in a dye or liquor tank, of a tank, a rotary shaft, flanged hubs secured thereto, longitudinally-slotted spokes secured to said hubs, and a frame for holding the skeins of yarn, having side arms formed of corresponding strips of metal slotted and adj ustable to each other for any length of skein, fitting into the groove of said spokes and securely locked in said spokes by the swinging arm 9, which fits by means of the hole in its bent end upon the pin '6.
